What is an event?
Before diving deep into the event naming convention, let us first understand what an event is. An event is an action performed by a user on a website or an app. An event could be a click on a particular link or a button. Let’s say someone clicks on CTA on your website, we will say an event has occurred.
Now let’s see what an event means for Universal Analytics and Google Analytics 4.
Universal Analytics (UA) Event
In Universal Analytics, events are user interactions on a website. These can not be tracked as a pageview in that session.
Let’s say a user comes to the website and watches a video. She then clicks the CTA and fills out the ‘Contact Us’ form. In such a scenario, Universal Analytics will report it as a pageview.
Event in UA consists of these four components:
- Event Category - The name given to a group of events. For example 'Website Videos', and ' CTA'.
- Event Action - The type of interaction that you wish to measure. For example ‘Contact Us Form Click’, and ‘Play Button’.
- Event Label - It is the additional information that you add about specific website elements. It is optional to add an event label.
- Event value - It is a numerical value and is assigned to an event. For example the number of downloads.
In essence, let’s say the website has three contact us forms and you wish to have data of all three of those, then category can be ‘Forms’, action can be ‘Submit’, and label can be the individual text on button or label.
Thus in universal analytics, an event is created for tracking the action within the web page. And the data is sent as a ‘hit’.
Type of hits defined in universal analytics:
- Pageview hit
- Event hit
- E-commerce hit
- Social interactions hit
- Exception hit
- User timing hit
- Screen hit (for apps)
Google Analytics 4 Event
As we know that in UA event is designed for tracking action within the web page. However, in GA4 event is designed to send all types of data. Be it action, user detail, page views, or any other information on the website.
In UA, data is sent as different hits. Whereas in GA4, everything is considered as an event.
Let us understand this difference with an example.
